There's nothing obviously wrong with this, and the fact that the
uploaded photo appears when you restart server supports that. Next
obvious thing to eliminate may be to check exactly where on your disk
the uploaded photo is actually written to. Perhaps it is not where you
expect, and what is happening is that it is being copied over to the
"right" location as part of your deployment/hosted mode running
procedure when you restart server. If you upload a photo and then
check where it goes while the app is still running, you should be able
to confirm that one way or another.
